I was following various live coverage (just as an interested observer) and it sounded like there were orientation issues with the Peregrine lander after separation. It seems possible tgat it could have used so much fuel trying to get solar panels and antenna aligned right, or even just doing unintended maneuvering, that it now cannot complete the lunar orbit maneuver, but is still otherwise working nominally.

A stuck open valve would explain all this. Not saying that is what happened, just that it's a theory that also fits.

One of the maneuvering engines gets stuck on while trying orient the solar panel at mission start. Loss attitude authority until it runs out of propellant. Now that it's done, control is restored, so power positive on the panels, but the fuel situation is beyond recovery.
